Ronin Network Ends Independent Sidechain Era... Official Transition to Ethereum Layer 2 on May 12, 2026

On May 12, 2026, Ronin Network will officially transition to an Ethereum Layer 2 (L2) solution, ending four years of independent sidechain operation. Executing at block height 55,577,490, this migration is a strategic move that fundamentally changes the network's security model and economic structure. It aims to resolve past concerns regarding decentralization and inflation while leveraging the robust security of the Ethereum mainnet.

The purpose of this migration is to strengthen security, tokenomics, and scalability.

On the day of the migration, May 12, 2026, Ronin Network is expected to experience approximately 10 hours of downtime. The specific timeframe is from 11:00 AM to 9:00 PM ET, during which all on-chain activities will be unavailable. The developers emphasized that all node operators must complete software updates before reaching the scheduled block height for the hard fork.

From Sidechain to Layer 2: An Inevitable Evolution

The background for Ronin abandoning its independent sidechain model and returning to the Ethereum ecosystem lies in the massive bridge hack that occurred in 2022. That incident exposed security vulnerabilities in the independent operation model, and since then, Sky Mavis has been considering a transition to an L2 structure that directly shares Ethereum's consensus algorithm. Through the new architecture, Ronin can inherit Ethereum's settlement guarantees, significantly increasing network safety.

• Securing robust security inherited from the Ethereum mainnet
• Improving tokenomics and enhancing RON token value through lower inflation rates
• Introducing new incentive and reward structures for developers within the ecosystem

In terms of technical choices, Ronin adopted Optimistic Rollup technology based on the OP Stack instead of Zero-Knowledge (ZK) Rollups. While ZK Rollups offer the advantage of fast finality, the OP Stack was evaluated as a more mature option at this stage due to its implementation simplicity and established ecosystem support. Sky Mavis is also reportedly keeping the possibility open for a future transition to zkEVM technology as the ecosystem matures.

The community and market are showing cautious optimism ahead of this transition. RON token holders and developers are waiting for the successful completion of the network transition, focusing on long-term value appreciation post-migration. In particular, this update is expected to play a key role in processing large-scale transactions for Ronin-based games, including Axie Infinity.

Impact on the Gaming Ecosystem and Future Outlook

As of 2026, Ronin is accelerating its efforts to realize its vision as the 'King of Modular Gaming.' This Layer 2 transition is foundational work to stably accommodate the high-frequency transactions required by modern blockchain games. Through this, Sky Mavis plans to provide an environment where game developers can build scalable dApps without security concerns.

Following the migration, investors and users should be mindful of the 'Challenge Window' period that occurs during withdrawals. Due to the nature of Optimistic Rollups, asset withdrawals may take approximately 7 days, which is part of the technical design for security. Ronin Network aims to solidify its integration with the Ethereum ecosystem starting from this transition and redefine standards for the Web3 gaming industry.

In conclusion, the hard fork on May 12, 2026, is expected to be a turning point where Ronin Network evolves beyond a simple gaming-specific chain into a powerful infrastructure sharing Ethereum's security. Stable updates during the downtime and the subsequent changes in tokenomics will be key indicators determining Ronin's future competitiveness.
